The word(s) "should" appears 190 time(s) in 163 verse(s) in Quran in Muhammad Pickthal translation.

(31) Ye will find others who desire that they should have security from you, and security from their own folk. So often as they are returned to hostility they are plunged therein. If they keep not aloof from you nor offer you peace nor hold their hands, then take them and kill them wherever ye find them. Against such We have given you clear warrant.

(32) Lo! Allah pardoneth not that partners should be ascribed unto Him. He pardoneth all save that to whom He will. Whoso ascribeth partners unto Allah hath wandered far astray.

(33) They consult thee concerning women. Say: Allah giveth you decree concerning them, and the Scripture which hath been recited unto you (giveth decree), concerning female orphans and those unto whom ye give not that which is ordained for them though ye desire to marry them, and (concerning) the weak among children, and that ye should deal justly with orphans. Whatever good ye do, lo! Allah is ever Aware of it.

(34) The people of the Scripture ask of thee that thou shouldst cause an (actual) Book to descend upon them from heaven. They asked a greater thing of Moses aforetime, for they said: Show us Allah plainly. The storm of lightning seized them for their wickedness. Then (even) after that) they chose the calf (for worship) after clear proofs (of Allah's Sovereignty) had come unto them. And We forgave them that! And We bestowed on Moses evident authority.

(35) O People of the Scripture! Do not exaggerate in your religion nor utter aught concerning Allah save the truth. The Messiah, Jesus son of Mary, was only a messenger of Allah, and His word which He conveyed unto Mary, and a spirit from Him. So believe in Allah and His messengers, and say not "Three" - Cease! (it is) better for you! - Allah is only One Allah. Far is it removed from His Transcendent Majesty that He should have a son. His is all that is in the heavens and all that is in the earth. And Allah is sufficient as Defender.

(36) O People of the Scripture! Now hath Our messenger come unto you to make things plain unto you after an interval (of cessation) of the messengers, lest ye should say: There came not unto us a messenger of cheer nor any warner. Now hath a messenger of cheer and a warner come unto you. Allah is Able to do all things.

(37) Lo! I would rather thou shouldst bear the punishment of the sin against me and thine own sin and become one of the owners of the fire. That is the reward of evil-doers.

(38) If only the People of the Scripture would believe and ward off (evil), surely We should remit their sins from them and surely We should bring them into Gardens of Delight.

(39) How should we not believe in Allah and that which hath come unto us of the Truth. And (how should we not) hope that our Lord will bring us in along with righteous folk?

(40) O ye who believe! Let there be witnesses between you when death draweth nigh unto one of you, at the time of bequest - two witnesses, just men from among you, or two others from another tribe, in case ye are campaigning in the land and the calamity of death befall you. Ye shall empanel them both after the prayer, and, if ye doubt, they shall be made to swear by Allah (saying): We will not take a bribe, even though it were (on behalf of) a near kinsman nor will we hide the testimony of Allah, for then indeed we should be of the sinful.
